[rescue] OS for ZFS?

I've run NexentaStor Community Edition (free, supports up to 16TB or 18TB
of storage) on a Dell deskside workstation/server (SC430, single core
Pentium or Celeron, 4GB RAM, two 1TB sata disks plus a flash drive for OS).
Not enough RAM to do dedupe, but it was pretty viable for mount points and

NexentaStor is built on descendants of Solaris, so Zachary would probably
be relatively comfortable with it. And they do regular development on it so
it's not a dead platform.

If you can bump your Dell up to 4GB or more, and make sure the drive
controller is supported (see http://zfs.bz/NexentaHSL for details), you can
probably get a bit done with it.

If you really want to work on ZFS with all its features and want to put
some money behind the effort, you can probably get a fairly substantial
dedupe-able box with a HP Microserver, 8 or 16GB or RAM, and NexentaStor or
the like. That'd set you back about $350+drives. Maybe less on your
favorite online source for used hardware. There are some nice hack options
on the hardware side on that machine as well (add 4-6 hard drives, esata
cards, fc mode, etc).

Hope this helps. (No formal affiliation with Nexenta, although a friend is
Global TME there.)
